I have found over the years that there are some mighty fine hog dogs out there in people's yards that are just regular old hog doggers not out for fame are money.
Speaking for the Yellers (go figure)
I have to go with what I have experienced and not what I have read in a sales promotion ad.
Having owned now a total of five papered dogs and one out of papered dogs throught several decades. I must conclude at best only one was mediocre and worth reselling. I myself am curious by nature and attempt to keep an open mind to the possibility of a long lineage line having worthy and capable dogs. However experience has proven that the greatest most impressive working ability dogs have came from no named individuals that simply keep dogs that prove themselves worthy of being fed by simply providing results.
If I had to pick a named line to represent the very best I have experienced.......nobody would know their name.....
X2 on your post above brother no matter what a double certified lineage paper says.
